To @ZZ 'wh/0111, 7225 may con/corni Be it known that I, HARRY C. LAssAM, a subject of the Queen of Great Britain, residing at 6 Kinver Road South, Sydenham, London, S. E., England, have invented certain new and useful Improvements Vin Glazing- Bars for Roofs, Skylights, dic., (for which I have obtained a patent in Great Britain, No. 4,492, dated March 3, lSQlJ of whichthe following is a full, clear, and venact specicaton.

This invention relates to lead or other metallic glazing bars or strips for holding and securing glass to sash-bars, astragals, or iron or steel bars of commercial shapes in the construction of roofs, skylights, and similar structures.

The present invention has for its objects to simplify and improve the prior glazing-bars or glass-holding strips; to provide the glazing-bar with a novel expansion-joint for the glass; to render the glazing-bar susceptible of general application to ordinary wooden or metal sash-bars, astragals, or iron or steel bars of commercial shapes now in use or to be hereafter constructed; to avoid the necessity of specially constructing sash-bars or astragals for receivingthe lead or composition glazingbar; to provide a durable and simple construction which can be very economically manufactured; to provide a novel construction of expansion-joint flanges or win gs which will prevent them from warping, While permitting expansion and contraction of the glasses; to provide a perfect dust and water tight expansion-joint in a glazing-bar or glassholding strip of ductile metal which is so constructed and is provided with such means that it can be conveniently and economically applied to the upper surfaces of sash-bars,

astragals, or iron or steel bars of commerical shapes that may be applicable and affords a substantial support for ladders or otherrests used in repairing roofs or skylights, and to provide a novel, simple, and efficient glazingbar or glass holding and attaching strip which can be drawn from lead or other ductile metal and be formed integral or in a Single piece with an improved expansionjoint, a central core, and a llat or flattened base or body having side flanges to embrace and hug an ordinary sash-bar or any other ordinary sash-bar or steel or iron bar Ofcommercial shape having a plain top surface or surfaces.

To accomplish all these objects my invention involves the features of construction and the arrangement of parts hereinafter described and claimed, reference beingmade to the accompanying drawings, in which- Figure l is a broken perspective View showing a portion ot' the improved glazing-bar, a portion of an ordinary metal sash-bar to which the glazing bar is applied,and portions of two glasses secured by the glazing-bar; and Fig. 2 is a similar view showing the improved glazing-bar applied to an ordinary wooden sashbar.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The numeral l indicates the dat or flattened base or body of my improved glazing-bar. This bar, as a unit, is drawn from lead or ductile metal or composition of metal and is formed integral or in a single piece with the pendent longitudinal edge flanges 2, the longitudinal upwardly-projecting edge ribs 3, the central longitudinal solid core-piece or rib 4, and the two inclined Wings 5, leading from the opposite sides of the solid core-piece or rib 4 and constituting the expansionjoint, as will more fully hereinafter appear.V The base or body l is flat or flattened to fit snugly and squarely upon the flat upper surface 6 of a sash-bar '7, and the flanges 2 hang from the opposite longitudinal edges of the base or body, so that they can embrace and hug the sash-bar. If the sash-bar is composed of an ordinary angle-iron, such as a T-shaped iron, as in Fig. l, the side flanges 2 can be bent under and pressed closely against the flanges 8 of the T-iron. If the sash-bar is of Wood, as in Fig. 2, the flat base or body 1 rests squarely on the top fiat surface 9 of the Wooden sashbar, while the flanges 2 embrace the bar and closely hug the parallel side surfaces 10 thereof and are fastened thereto by nails, screws, or other suitable means. The formation of the base or'body with the pendent longitudinal edge ilanges 2 enables the glazing-bar to be conveniently and firmly applied and secured on ordinary sash-bars, such as are now in use in roofs or skylights, which ICO is very advantageous over that class or type of glazing bars or strips requiring speciallyconstructed sash-bars which are segmentallyshaped in cross-section.

The longitudinal edge ribs 3 are substantially triangular in shape to facilitate drawing the same, and they rise above thertop surface of the base or body sufliciently high to act as supports for the approximate edge portions of the glasses 12.

The inclined Wings 5 extend from the corepece or rib 4, and start therefrom at points below the top edges of the triangular glass supporting ribs 3. The Wings also extend approximately horizontal, as at 5a, and these extensions are uniformly increased in thickness from their angles or corners 13 to their outer edges 14 for the purpose of effectually preventing warping of the metal due to heat or any other cause. The Wings 5 stand at an angle to the eorepiece or rib 4 to provide a space between the Wings and core-piece or rib sufficient to permit the Wings to move toward and from the -core-piece or rib, so that when the glasses 12 are in place, as shown, and the extensions 5a are cemented to the edges of the glasses, if the latter expand or contract, the wings 5 can readily move or yield toward or from the core-piece or rib. By this means I provide a dust and water tight expansionjoint in a glazing-bar having pendent flanges to embrace au ordinary sash bar. 1t has heretofore been proposed to provide a lead glazin g-stri p with flanges to lap over the edges of the glasses and hold the latter down upon glass-supporting rests; `but in such devices the strip is made of a sheet of comparatively thin lead folded about the segmental head of a specially-constructed sash-bar. This is expensive, intricate in construction, diiicult to manufacture in a durable manner, and requires specially rolled or bent sash bars, Whereas my improved glazing bar or strip, With its expansion-joint Wings all integral and in one piece, can be cheaply made by ram ming or drawing through a die in an ordinary leaddrawing machine. It is simple, easily manu faetured, and is strong, durable, and applica ble to ordinary sash-bars or steel or iron bars of ordinary commercial shapes or Wooden astragals.

Having thus described my invention, what I claim is l. As an improved article of manufacture,

a glazing-bar of ductile metal formed integral with a base or body l having longitudinal, pendent flanges 2 at its edges for embracing an ordinary sash-bar or iron beam, longitudinal edge ribs 3, longitudinal, central corepiece e, and inclined Wings 5 extending from the core-piece and movable to and from the latter to form an expansion joint, substantially as and for the purposes described.

'2. A glazing-bar drawn in a single piece of ductile metal with the base l, pendent side ilanges 2, upwardly projecting edge ribs 3, a central, vertical core-piece 4, and inclined wings 5 leading from opposite sides of the core-piece from points below the level of the upwardly-projecting edge-ribs and formed With extensions 5"I which gradually increase in thickness toward their outer edges to prevent Warping, said Wings i being movable toward and from the core-piece to form an expansion joint, substantially as and for the purposes described.
